Be it known that I, HENRY C. MILLER 2i citizen of the United States, residing at Waterford, in the county of Saratoga and State of New York, have invented certain new and useful Improvements in' Motors for Specification of lletters Patent.

Talking-Machines, of which the following is a specification.

This invention relates to motors designed primarily for talking machine -and more particularly to the various details of construction thereof.

The prime object of the invention is to providea motor mechanism provided with specific winding means, and means for re ducing to a minimum the parts, whereby the noise incident to the running of the mechanism-is greatly reduced.

With motors now used in connection with talking machines, the mechanism is arranged so that several selections may be reproduced with one Winding, which causes considerable annoyance, inasmuch as the attendant must be'in proximity to the machine to stop it,

otherwise the stylus running over the record beyond the groove produces a very unpleasant sound.- Then again, the first selection is reproduced in the proper .time,.hut the subsequent selection will be slower and not up to: he standard. This is due to the fact thatthe motor as it runs down necessarily becomes weakerand the record is therefore caused to travel slower. But .as-this efiect is so well known' in the art it is not deemed necessary to further amplify it more than to state broadly that it is one of the objects of my present invention to cure the defect. To meet this weakness in structure, I provide means, such for instance, as a lever, having connected with; it a motor, that by movement of said lever a determinate distance, prearranged in accord with a particular record, and then released, when the end of the selection on the record is reached, the machine will be automatically stopped and the attendant as well as the audience will enjoy the reproduction.

Other objects and advantages will be hereinafter referred to and particularly pointed a detail View of a friction clutch used in con- ATliTih-tiifi lfiiil.

"nection with my invention. Fig. 5, is a de-j tail view. Fig. 6, is detail view of a slightly different form of indicator.. Fig, 7 is a detail plan view partially in sect-ionlof the governor. V v

The numeral 1, indicates a casing 2, the top of the same, and 3, a frame" supported. lily the top. A bracket 4, depending: from the frame 3, hastormed in its lower portion bearings 5, in which is mounted a power shaft 6. Fast on one end of said. shaitis a member 7, of a friction clutch 8, and entire opposite end is a worm gear 9. gear 9, meshes with a Worm 10, on a countershait 11, mounted in hearings formed hracket 19., secured to frame 3. he counter shaft is further supported at its lower end by a conical bearing 13, seated in the bracket 12, and fixed in position by -a' set screw 1%.

The lower end of'bracket 12, is formed into with a governor 18. I

The clutch 8, may be of any form, but the construction shown in the drawing consists of a cup shaped, member and revolving within this cup shaped ,member, is a disk 35, having a series of notchesSG, with inclined faces. as indicated at. 3i',,betw'een each of which and the inner portion of the flange of the member 7,; operate balls or rollers 38, having tension springs 39, to force them into operative position. On the outer face of the disk 35, is fasteneda pinion-4&0. Pivoted on the inside of the case 1, at 41,

is a lever 42, formed with ahandle 43, which extends through an opening 44$,in the top 2,

adjacent which is a. slotted plate 45 providedcage with pinion 40, as clearly shown in Figs. 2, and 3, and connected ,with the epp'osite side of said leve j isfal inotor spring This motor,.as shown in Fig. 2, he in the form of a spring, or as shown in Fig.

3, may he in the form of. a weigl tfligl. viously a coil spring will not bind. l ke a fiat spring, asv ingnotors now used for, talking machine. purposes.

On the upper end of the counter sh aft 11.,

which extends through the frame 13 mounted. a turntable 50, for supporting record 51.

As hereinbe'fore indicated, I propose to .L

arrange my improved mechanism so that i ingv to the length of the selection thereon. That is to say, each record. will have applied to it a character, corresponding to a similar character on the plate 4.5, and when a par-' ticular record is being used, the lever will be moved to the character adjacent plate 45, and the motor will be set so as to play but one piece. When [the spring returns lever 42, to normal position said lever will contact with the plate45, at the end of the slot 44, hence. the mechanism will be stopped. In this manner I avoid the usual grating of the stylus over the record and at the same time am enabled to start a selection and leave the machine that the operator as well as the audience may. enjoy the benefits of the selection. This avoids the necessity of the operator being in proximity with the machine to turn off the motor after the selection hasbeen reproduced.

When the lever 42,-is moved in the direction of the arrow 21,.Fig. 2, the balls or rollers 38, are caused to be moved into the widest portion of 'the notches 36, hence motion is not imparted to the shaft 6, but immediately upon release of said lever, the motor spring or weight, as the case may be, acting on lever 42, in the direction of arrow I), Fig. 2, imparts motion to said shaft 6. The motion to the shaft 6, is transmitted through worm gear 9, to the worm l0, hence to the counter shaft 11, and then to the turntable.

In Fig. 6, I have shown a different form of indicator, which consists of a disk 100,. with indicating characters thereon, and a stop 101. A pointer 102, on the face of the diskcotiperates with it to determine the time the motor will be in operation. .levolving with the disk, or formed with it if desired, are teeth 103, which mesh with a worm 104. on a shaft 105, which in turn is connected with the motor (not shown in this figure.)

What I claim is:

1. A motor for a talking machine comprising a counter shaft, :1 power shaft, means for operating the counter-shaft from the power shaft, a lever arranged for man ual operation in one direction, means for naming thelever in the opposite direction, a connection between the lever and power shaft to operate the latter in the movement of the lever under the influence of its opeating means, means for limiting movement of the lever in one direction, and means for gaging the normal movement of the lever to regulate the extent of its mov ment under its operating n'icans.

9.. A motor for a talking machine comprising a counter-shaft, a power shaft, means for operating the counter-shz'xft from the power shaft, a lever arranged for man ual operation in one direction, means for moving the lever in the opposite direction, a connection between the lever and power shaft to operate the latter in the movement of the lever under the influence of its operating means, means for limiting movement of the lever in one direction, and a graduated dial cooperating with the lever to gage its manual movement. A motor for a talking machine comprising a counter shaft, a worm on said counter shaft, a power shaft, a gear on the power shaft, said gear meshing with the worm, a lever arranged for manual operation in one direction, means for moving the lever in. the opposite direction, a gear and clutch connection between the lever and power shaft to operate the latter in the movement of the lever under the influence of its operating means when the lever is manually moved and also means to connect the gear connection with said power shaft when the lever is'moved in the opposite direction, means for limiting movement of the lever under its'operating means, and a governor operating in connection with the counter shaft for regulating movement of the latter. 4; A motor for a talkingmachine.com prising a counter shaft, adjustable means for centrally supporting said counter shaft, a bearing for the counter shaft above said central adjusting means, a power shaft, gearing between the power shaft and the counter shaft, a gear and clutch on thepower shaft, a lever having teeth engaging the gear on the power shaft and arranged for manual operation in one direction, means for moving the lever in the opposite direction, and means for limiting the movement of the lever.

A motor for a talking machine comprising a power shaft and gearing, a lever arranged for manual operation in one direc tion, means for moving the lever in the opposite direction, a connection betweeirthele ver and power shaft to operate the latter in the movement of the lever under the influence of its operating means. and means for gaging the movement of the lever to regulate the extent of its moven'ient under its operating means.

in testimony whereof I have signed. my ame to this specification in the presence of n two subscribing witnesses.
